[Media] Slint (and Rust) running on my jailbroken Kindle Paperwhite.

I wanted to make a dashboard for Home Assistant on my Kindle, and since I know Slint from a previous project I was curious to see if I could use that. This resulted in a slint-backend for kindles (probably not a lot of them for now, as I only have the one device to test on).
